Answer #1

Difference between the Cancerous cells and normal cells:

  • Cancer cells develop out of normal body cells and tissues.Over a period of years,damage to the DNA of healthy cells disrupts their orderly growth, leading to the formation of malignant tumors.
  • The cell cycle, the process by which cells progress and divide, lies at the heart of cancer. In normal cells,the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides.
  • Whereas in the cancerous cells the cell cycle is out of control and the cells divide rapidly and continuously.
  • Cancer is an unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
